Product Details

PR-ZR (Yellow zirconia series)

PR-ZR (Yellow zirconia series) is a yellow yttrium-stabilized zirconia structural member,According to customer's demand, we can precisely process structural parts with high temperature resistance and corrosion resistance. High wear resistance and other advantages, can be used stably in complex working conditions.

1. Characteristics and advantages of product materials

• Excellent corrosion resistance, suitable for all kinds of acid and alkali conditions;

• Super hardness and fracture toughness of ceramic materials, products are not easy to wear;

• Neutral physicochemical index, no pollution to the ground material;

• Complex 3D modeling surface, five-axis five-joined surface.

2. Application

Suitable for tower wheels, wire drawing wheels, valve cores, plungers, molds, cutters, shafts, bearings, bushings, sealing rings, etc.
